Transverse fillet welded joints are designed for

Definition: A transverse fillet weld is a weld where the axis of the weld is placed perpendicular to the direction of the applied load.

Load action: In a transverse fillet welded joint, the load is applied across the throat of the weld, which results in shear stresses being developed in the weld material.

Design basis: Since the primary mode of failure for this type of weld is due to shear across the throat area, the joint is designed considering the shear strength of the weld metal.

Reason: Designing for shear strength ensures that the weld can safely resist the applied load without shear failure, thus maintaining the integrity of the joint.

Conclusion: Transverse fillet welded joints are always designed based on their shear strength.
